A Prime Number: is a whole number greater than 1 that has exactly 2 factors, 1 and itself.Examples: 2 = 1 × 2 3 = 1 × 3 5 = 1 × 5 and 7, 11, 13 …
A Composite Number is a whole number greater than 1 that has more than two factors.
Examples: 4 = 1,2,4
6= 1,2,3,6
and 8, 9, 10 …

Prime Factorization: Every composite number can be written as a product of prime numbers. This product is the prime factorization.You can use a factor tree to find the prime factorization.
